12' Claims. (Cl. 118--300) This invention relates to spattering or likedistributing means or applicators for paints, plaster of Paris, plasticmaterials and similar viscous masses to be applied for adherence to asurface.

It is one of the primary objects of this invention to provide meansaffording marked economy and easy ma- .nipulation of an applicator fordistributing or applying viscous masses to a surface for covering orcoating the same, either partly or entirely, for protective, decorativeor like purposes.

It is another object of the present invention to provide meansfacilitating the construction of a portable applica- .tor from whichpredetermined quantities of particles of a viscous mass may be dispensedto. thereby obtain, if so desired, a predetermined pattern along asurface to which the applicator is directed.

It is still another object of this invention to. provide meanscontributing to a very efficient and simple applicator constructionwhich requires only a few parts, may be either motor-driven orhand-operated, and has adjustable discharge openings to thereby vary theextent of application of a viscous mass toa SUlfflCfltOubfi treated.

A further object of the invention resides in-the provision of meansmaking it possible to; support the applicator at predetermined angularpositions relative to. the surface toube treated and at a certaindistance therefrom, means being provided for continuously moving theapplicator along saidsurface.

It is. still a further object of this invention to. provide meansconducive to a very efiicacious applicator for spattering masses againsta surface to be treated and with variable slinging or impelling; forces.

Yet another object of the invention. is to provide means envisagingcertain improvements in carrying out the spattering of viscous massesonto an even or uneven surface and: in. a predetermined fashion, wherebyfloor surfaces, overhead. ceilings and other wall surfaces may bereadily treated and within. a minimum of time and without anysubstantial Waste.

Still a further object of the present invention is; to provide meansaffording interchangeability and disassembly of applicator parts forcleaning purposesand for feeding different kinds of masses to, mixingthe same in, and discharging them from theapplicator.

Still a further object of the invention is to provide means ensuringhomogeneous mixing operation. for a plurality of viscous, flow-resistantor plastic masses in a reservoir, which may be integral with or mayform. a separate part of the applicator housing and thereafter dischargeof such thoroughly mixed masses from said housing under force or impactagainst a surface to be treated.

A further object of the invention resides in the provision of meansrendering the possibility of applying adhesive or like mass or masses toa surface to be decorated in various configurations, thicknesses andlayer formations.

These and other objects of the invention. will become Patented Dec. 23,1958 2 further apparent from the following detailed description,reference being made to the accompanying drawings, showing preferredembodiments of the invention.

In the drawings:

Fig. I is a partial sectional vertical view through an applicatorembodying the invention.

Fig. 2 is a top plan view of the applicator of Fig. l, closure platesthereof being shown in dotted lines.

Fig; 3 shows a similar top. plan view as Fig. 2 with the top platesshown in full lines and. applied in one opera,- tive position, theapplicator being shown on a reduced scale,

Fig. 4 shows a cross sectional view taken along lines 44 of Fig. 3.

Figs. 5, 6, show, respectively, top plan views o a. S tion ofa surfaceafter treatment with the applicator made in accordance with theinvention.

Fig. 7 illustrates in side view the applicator of Fig. I mounted on atripod; showing schematically the applicaterin pera n.

Fig. 8 is a fragmentary view partly in section showing the mountingofthe blades of the applicator in the drum body of the latter.

Fig. 9 shows an enlarged sectional view taken along lines 9-9t of Fig.8.

Referring now more particularly to the drawings and, in particular, toFigs 1 and 2 there is disclosed an applicator 10 having a housing 11which. is U-shaped in cross section with a substantially aroua-te bottom12, opposite side Walls 13, 14' and rear wall 15. To rear wall 15 thereis attachedexteriorly thereof at 16, 1-7' a handle 18 for graspingapplicator 10 to thereby maintain the same in an operative position orto carry it from; place to place. Bottom 12 is provided with a suitablebase frame: 1 9 having a central screwathreaded opening 2 0 for apurpose later referred to.

The side walls 16, 14- of theapplicator l0. support a transverse shaft21 to which is connected a crank 22 with handlers. for operating thesame. Instead of a crank and handle arrangement 22, 23 a small motor maybe employed to continuously or intermittently drive said shaft 21 Shaft21 is supported in suitable bearings 24, 25 which contain glands (notshown) in order to ensure liquid or fluid-tightness. On shaft 21 thereis mounted. within housing 1.1 a hub or drum body 26, in which there areprogressively. inserted at spaced intervals a plurality of pairs ofsomewhat spaced, springy fingers or blades 21, 218 diverging toward theouter extremities thereof and. made of steel, plastic or plasticcomposition, slots or similar openings. 29,. being provided in drum 26to retain the respective pairs of the flexible blades in fixed positionas can. be more clearly visualized from Fig. 8. Instead of two, threeormore springy or flexible blades. may be inserted in each r espectiveslot and in predetermined, succession, as may be visualized from theplacement of the ends 30x, 30y, 30z of said blades (Fig. 2), bunches ofblades 30,, 30a, 30b, 30c being seen in Fig. 1.,

Fig. 9 shows, for example, blades 27 and 2 8 somewhat curved incross-section so that any material M lifted out of the reservoir 31 ofapplicator 10 may be first collected by the blades forming resilientapplicator or catapulting means and retained within .the respectivespace between these blades along substantially their entire length fromthe hub 26 to the outer extremities or free ends of said is adjustablyattached by means of wing screw 32 an abutment plate 33 having aninwardly projecting portion 33a and an upwardly and inwardly directedgrip portion 33b for facilitating adjustment of plate 33 to differentpositions (as indicated in dash and dot lines in Fig. 1).

Blades 30, 30a etc. during rotation of handle 23 and drum 26 in thedirection of arrow A first pass through reservoir portion 31 where theycome into contact with I viscous or flow-resistant mass M, thence abutagainst spattering plate portion 3311, at which the blades are firstbent into a position as clearly seen in Fig. l at 30' and thereafterreleased to a position indicated by blades 30, 30a, 30b etc., wherebythe material M after having been previously moved lengthwise of theseblades is thrown with great force and spattered along paths 35, 36 and37 toward a surface S (Fig. 7), thereby building up a coating orcovering C of predetermined thickness thereon.

As can be visualized from Figs. 1 and 2 the housing 11 has an open topat 34 and is preferably reinforced thereat by a curled rim 34a.

According to the invention the side walls 13, 14 may optionally beprovided with lateral, outwardly directed flange pieces 13a, 14a foradjustably receiving thereon pattern plate portions 38, 39 which may beadjusted to each other and relative to housing 11 by means of slot andwing screw arrangement 40 as may be readily visualized from Figs. 3 and4. The effective edges of pattern plates 38, 39 may be, for instance,scallop-shaped as at 41, 42, whereby a predetermined width or opening 43between them may be obtained through which viscous mass M may bespattered from within housing 11 therewithout and against Wall surface Sin a fashion, as exemplified at C in Fig. 6, whereby C signifies athinner layer and C a relatively heavier layer of spattered coatings.

Instead of scallop-shaped edges 41, 42 straight edges may be employed,to thereby obtain a coating configuration, as more clearly seen in Fig.at C, which consists of portions C C, which are disposed to each otherin At least one of the legs, such as leg 48, may be provided with aballor wheel-shaped end 49, by which the applicator 10 may beequidistantly spaced from surface S, while the applicator is being movedin predetermined angular position relative to tripod surface 44, asseen.

The applicator housing as herein disclosed and shown in the drawings maybe made of stainless steel, plastic or light-weight material, ifdesired, so that easy transportation from place to place may be had.

It has been found in practice to fill the bottom reservoir 31 with massapproximately up to the level of the drum body or carrier 26 dependingupon the position of the surface to be treated.

In order to use the device for spattering a floor surface with concrete,metallizing substance, rubberized or linoleum mass or masses, it ispreferred to fill up housing 11 approximately to A or less than /2 ofits effective capacity.

It will be further understood that upon retraction of regulator orabutment plate 33 to a position which may be marked on the outer surfacethereof, in which abutment piece or spattering plate portion 33a willnot come into contact with the ends of the blade means, the resilientapplicator or catapulting means may first be employed to thoroughly andhomogeneously mix the mass or masses M contained in the reservoir ofhousing 11 and may then be used to effectuate spattering operation uponadjusting abutment member 33a relative to said ends of the blade meansthereby attaining sufiicient flexing action for final spattering throughthe top or spout of said housing.

It is understood that material or mass M will adhere prior to spatteringto both surfaces of each of said blades and will collect within spacesbetween individual blades grouped in bunches or tufts.

Instead of grooved, springy blade means bristles or like flexibleelements may be employed which are sufficiently resilient and lift apredetermined quantity of mass out of the reservoir during operation.These blade means are preferably arranged on drum body 26 inpredetermined or changeable fashion (staggered or displaceablerelation).

It can thus be seen that there has been provided according to theinvention a portable applicator for directing under force a pasty massagainst a surface to be treated comprising a portable housing having aspout, a rotatable carrier mounted in said housing, a reservoir for saidmass communicating with said housing, and abutment member adjacent saidspout and spaced from said carrier and said reservoir, flexible blademeans distributed over and extending from said carrier into saidreservoir and toward said abutment member, whereby upon rotation of saidcarrier said blade means come successively in contact with said mass andthen with said abutment member to be flexed by the latter, said blademeans upon release from said abutment member impel or catapult massparticles through said spout against said surface against which saidspout is directed.
